BUILDING-LIGHT.

Specification of Letters Patent.

Patented July 28, 1908.

` Application led October 7, 1907. Serial No. 396,221. i

To all whom it may concern:

i Be it known that I, PHrLIP'ScHwIcKART, a citizen of the United States,and a resident of thecity of NewYork, borough of Brooklyn, in the countyof Kings and State of New York, have invented a new and ImprovedBuilding-Light, of which the following is a full, clear, and exactdescription.

The invention relates to walls, skylights, floors and other parts ofbuildings, and its object is to provide anew and improved bulldinglight,which is simple, durable, eX- ceedingly strong in construction, cheap tomanufacture, easily and conveniently set up, and arranged to insure aproper and uniform distribution of the rays of light.'

The invention consists of novel features and parts and combinations ofthe same, which will be morefully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention` is represented in theaccompanying drawings forming a part of this specification, in

Awhich similar characters of reference indiment, a portion of thecementitious material being broken out; Fig. 2 is a sectional sideelevation of the same on the line 2-2 Vof Fig. l. Fig. 3 is an enlargedsectional side lelevation of part of the improvement on the line 3-3 ofFig. l; Fig. 4 is an enlarged sectional side elevation of part of theimprovement on the line 4 4 of Fig. l, and Fig. 5 is an inverted planview of one of the lenses.

The lenses or glass lights A are supported on the spaced cross bars B ofa skeleton frame having side beams C supporting the cross bars B, eachside beam being made in one or more endwise abutting sections, accordingto the length of the skeleton frame. As illustrated in the drawings, thecross I bars B and the sidebeams C are made of T- irons, the horizontalmembers C of the side beams C being placed downward, and adapted to reston suitable foundations. The vertical members C2 of the side beams C areprovided with slots C3, into which fit the vertical members B of thecross bars B, the ends of the horizontal members B2 of the cross bars Bresting on the top of the vertical members C2 of the'side beams C, asplainly shown in Figs. 3 and 4.

The cross bars B on opposite sides of the joints C4 between the sectionsof a side beam I C, and near the reduced portions B3 on said cross bars,are connected with each other by a connecting and spacing bar D, formedat the under side with recesses D, fitting over the horizontal membersB2 of the said adjacent cross bars B (see Figs. l and 4), to hold thesaid cross bars the desired distance apart, and to couple the sectionsof a side beam C with each other. By the arrangement described anexceedingly simple and durable skeleton frame, for supporting the lensesor glass-lights A is provided, and which skeleton frame requires noscrews or other fastening means for holding the parts in position.

Each of the lenses or building lights A is provided with a conical toportion A and a square bottom portion A2, t e said portions A and A2forming shoulders or under-cuts A3, adapted to rest on the top of theopposite sides of the adjacent cross bars B to support the lenses. Eachof the top portions A is provided with an annular bead A4. Now in vorderto place the lenses A in position on the cross bars B, the horizontalmembers B2 thereof have cut-out portions B3 near one of the side beamsC, to allow of conveniently slipping the lenses in place on the adjacentcross bars B.

The lower portions A2 of the lenses are preferably pyramidal, andproject below the cross bars B, and the adjacent cross bars B are spacedapart such distances that when the lenses A are in position, the sidesof the square bases of adjacent lenses abut in both a transverse andlongitudinal direction, thus forming an under surface of glass of anunbroken continuity. The lower pyramidal portion A2 of each lens isprovided with a recess Af, the roof A6 of which is convex, and the sidewalls are formed by prisms A7 eX- tending from the marginal edge of theroof 'A6 downwardly and outwardly to the beveled under sides A8 of thesquare base of the lens, as will be readily understood by reference toFig. 5. By the arrangement described, the rays of light are properlydeflected and distributed in the space below the building light, so asto highly illuminate the said space.

A cementitious material E, such as plastic cement, is poured into thespace between the sides of adjacent lenses or glass lights A, tocompletely embed the cross bars B, the said cementitious material beingflush at the top with the upper surfaces of the lenses A. By

having the conical top portion A of each lens provided with the annularbead A, it is evident that the material E is securely anchored inposition on the top portions A of the lenses. By the arrangementdescribed, an exceedingly strong and durable building light is produced,which is completely water and moisture-proof, and is capable ofdistributing the rays of light uniformly and over a large area.

The building light shown and described can be cheaply manufactured,quickly set up and used for various purposes, such as 1ccl vers forvaults, for skylights, floors and the Having thus described myinvention, I claim as new and desire to secure by Letters Patent:

l. A building light, comprising side beams having spaced notches,cross-bars fitting into the said notches, lenses supported on the saidcross bars and projecting above and below the same, the under side ofthe lenses forming a surface of unbroken continuity, and a cementitiousmaterial illing the spaces between the side walls of adjacent lenses andembedding the said cross-bars.

2. A building light, comprising spaced side beams of T-iron, and havingthe vertical member provided with spaced notches leading out through theedge of the same, crossbars of T-iron and having their vertical meinbersfitting the said notches, the horizontal member resting on the verticalmembers of the said side beams, and lenses supported on the said crossbars.

3. A building light, comprising spaced side beams of T-iron, and havingthe vertical members provided with spaced notches, cross bars of '-ironand having their vertical members fitting the said notches, thehorizontal member resting on the vertical members of the said sidebeams, and lenses supported on the said cross bars, the lensesprojecting above and below the cross bars and their undersides forming asurface of unbroken continuity.

4. A building light, comprising spaced side beams of T-iron and havingits vertical member provided with spaced notches, cross bars of T-ironand having their vertical members provided with spaced notches, crossbars of T-iron and having their vertical members f1tting the saidnotches, the horizontal member resting on the vertical members of thesaid side beams, lenses supported on the said cross bars, the lensesprojecting above and below the cross bars, and their undersides forminga surface of unbroken. continuity, and a cementitious material iillingthe spaces between the side walls of the said lenses and embedding thesaid cross bars.

5. A frame-work for building lights, comprising spaced side beams eachhaving a base and an integral vertical member provided with notchesleading out through the edge of the same, and cross-bars supported onthe said side beams and having a vertical member'iitting thesaidnotches, the said cross bars having horizontal members resting onthe top of the vertical members of the said side beams.

G. A frame-work for building lights, comprising spaced side beams eachhaving a base and an integral vertical member provided with notchesleading out through the edge of the same, cross bars supported on thesaid side beams and having a vertical member [itting the said notches,the said cross bars having horizontal members resting on the top ol thevertical members of' the said sidc` beams, andv lenses having shouldersresting on the sides of the horizontal members of the cross bars.

7. A frame-work for building lights, com- 'prising spaced side beams,each having a base and an integral vertical member provided withnotches, cross bars supported on the said side beams and having avertical member iitting the said notches, and a connecting and spacingbar for engagement with the adjacent cross bars at the joint ot the sidebeams.

S. A frame-Work for building lights, comprising` spaced side beams, eachhaving a base and an integral vertical member provided with notches,cross bars supported on the said side beams and having a vertical memberfitting the said notches, and a connecting and spacing bar havingrecesses on its under side for engagement with horizontal members of thesaid cross bars located on opposite sides of the joint between the sidebeams.

In testimony whereof l have signed my name to this speciiication in thepresence ol' two subscribing witnesses.
